HAMILTON - The high school volleyball coach who pleaded guilty to sexual misconduct involving a student has lost her teaching license.

Hilary Dattilo, 31, pleaded guilty earlier this year to gross sexual imposition, a felony. Dattilo was scheduled to be sentenced Tuesday, but her hearing was pushed back to July 31.

Authorities say Dattilo, who was also a science teacher, "did purposefully compel a student enrolled at Hamilton High School to submit to the touching of an erogenous zone for the purpose of sexually arousing or gratifying either person."

Neither police nor school officials have said exactly what happened. Authorities did say the investigation started with concerns from a student's parents.

The criminal activity happened last fall, according to court records. The victim was a 16-year-old female.

As part of her plea deal, Datillo must register as a sex offender and complete an in-person verification process once a year for 15 years.

The Monroe resident also can't live within 1,000 feet of a school, according to court documents.

Some of the evidence collected in the case included videos from volleyball games. Other evidence included messages on a mobile app designed for school communication.

Dattilo started working at the school district in August. She has been on unpaid leave since December and will not teach at the district again, according to Hamilton Schools Superintendent Larry Knapp.
